Evaluating the influence of geographical location between cellular end-users and data center on latency in E-UTRAN network

Today, customers are connected to mobile networks from their smartphones, laptops, and their demand of traffic is increasing continuously. In order to satisfy their requirements, mobile operators are working on improved network topology which leads to increased bandwidth, and generally improves Quality of Experience (QoE). All of the requirements listed below require expensive hardware updates. Another way to improve already existing topology is to implement software updates. Proposed modifications implying novel algorithms including the implementation of Quality of Services (QoS) which lead to situation that data processed in operators' data centers would be improved. This work elaborates on if and how cellular users and their required services are influenced by the geographical location and their distance to the mobile data center. The other research question is an influence of the traffic volumes which have to be processed on the data center side. The evaluation is executed in live AT&T LTE cellular network and further compared with previous results from 3G and 4G networks. © 2016 IEEE.
